7 Miitiro Yekuyedza Kuramba Kwemamiriro ekunze kwePowder Coatings

Iko kune 7 zviyero zvekuyedza weathering kuramba kwe kupfeka hupfu.

• Kupokana nedhaka
• Kuwedzera kuchembera uye kusimba kweUV (QUV)
• Munyu
• Kesternich-test
• Florida-bvunzo
• Humiditytest (inopisa mamiriro ekunze)
• Chemical Nemishonga

Kupokana nedhaka

Zvinoenderana neyakajairwa ASTM C207. Imwe dhaka ichaunzwa yakasangana neupfu hwekuputira panguva ye24h pa23 ° C uye 50% hunyoro hunoenderana.

Kuwedzera kuchembera uye kusimba kweUV (QUV)

Muyedzo uyu muQUV-weatherometer ine 2 macycles. Iwo akavharidzirwa testpanels ari 8h akaoneswa UV-mwenje uye 4h kune condensation. Izvi zvinodzokororwa panguva ye1000h. Ese 250h mapaneru anotariswa. Apa iyo coating inoedzwa paruvara- uye gloss retention.

Munyu wekutsvaira kwemunyu

Zvinoenderana nezviyero ISO 9227 kana DIN 50021. Iyo hupfu yakafukidzwa mapaneru (ane muchinjiko weandreas wakakweshwa nepakati kuburikidza nefirimu) inoiswa munzvimbo inodziya ine mwando uye yakapfapfaidzwa nemunyu. Muedzo uyu unoongorora mwero wedziviriro kubva pakuputira kusvika pakuora munzvimbo ine munyu (semuenzaniso pagungwa). Kazhinji testcase iyi inotora 1000h, cheki ichiitwa 250h yega yega.

Kesternich-test

Zvinoenderana nezviyero DIN 50018 kana ISO3231. Inopa chiratidzo chakanaka chekupikisa kwekuputira munzvimbo yeindasitiri. Kwenguva yakati peni yakavharwa yebvunzo inoiswa munzvimbo inodziya ine hunyoro, ine sulfur dioxide. Muedzo uyu uri kuita 24h-cycle ine zvidzoro 250h yega yega.

Florida-bvunzo

Pakati pegore risingasviki 1 ma testpanels akavharidzirwa anoratidzwa kune yezuva uye ine hunyoro nharaunda yeFlorida, USA. Kubwinya pamwe nekuchengetedza kwemavara kunoongororwa.

Humidity test (kupisa kwemamiriro ekunze)

Zvinoenderana nezviyero zveDIN 50017 kana ISO 6270. Inouraiwa mukamuri ine nharaunda ine hunyoro hwakazara, pane yakatarwa tembiricha uye kazhinji panguva ye1000h. Ese 250h kudzora kunoitwa pahupfu yakafukidzwa mapaneru uye Andreas-muchinjikwa wakakwenya nebanga kuburikidza nefirimu iri pakati. Muedzo uyu unoongorora kudzika kwehunyoro uye ngura munzvimbo ine mwando.

Chemical Nemishonga

Kemikari kuramba Inowanzoongororwa pamajasi anoiswa pasi pekugadzirisa, kusangana nemishonga yekuchenesa kana makemikari. Mamiriro ezvinhu akaenzana haana kunyorwa. Saka, mugadziri wehupfu anogadzirisa mamiriro acho mukukurukurirana nemushandisi kana mutengi wekupedzisira.

Kuti uedze kupikisa kwemamiriro ekunze kweupfu hwekuputira kwakakosha zvakanyanya mukushandisa poda yekuputira.
